What's the difference between wave welding and manual welding?

The difference between wave welding and manual welding;

First, the welding quality

From the point of welding quality alone, wave welding must be better than manual welding. Although the quality of manual welding has been qualitatively improved with the application of high-quality intelligent soldering iron, there are still some uncontrollable factors. For example, the control of solder quantity and welding wetting angle, the guarantee of welding consistency, and the requirements of tin passing rate of metallized holes. Especially when the lead of components is plated with gold, it is very troublesome to remove gold and wire tin from the parts that need tin-lead welding before welding.

Second, the welding efficiency

In the traditional sense, manual soldering iron welding requires many people to use point-to-point welding for PCB. Selective wave soldering adopts assembly line industrial batch production mode, and welding nozzles with different sizes can be welded in batches by dragging welding, and the general welding efficiency is several times higher than that of manual welding.

Thirdly, the flexibility of welding operation.

Wave soldering uses programmable movable tin cans and various flexible welding nozzles, so some fixing screws and reinforcing ribs on PCB surface can be avoided by programming during soldering to avoid damage caused by contact with high-temperature solder, and customized pads are not needed. Therefore, it is especially suitable for multi-variety and small batch production methods, especially in aerospace, military and other fields, and its application prospect is very broad! When welding with selective wave soldering, the welding parameters of each solder joint can be "customized"

To sum up, compared with manual welding, wave soldering has many advantages, such as good welding quality, high working efficiency, flexible operation, low defect rate, less environmental pollution, diverse welding components and so on. It is the best choice for PCBA welding of highly reliable electronic products to replace manual welding.
